中文摘要	Superconductive La2CuO4+delta with T-c similar to 40 K has been obtained by chemical oxidation using NaClO solution. The oxygen-decrease processes have been studied during the thermal treatment processes at different temperatures. The material separates into discrete phases with different transition temperatures for samples treated at 100 degrees C consistent with the oxygenation process reported previously. However, Tc decreases continuously in samples treated at 300 degrees C, similar to the superconducting properties of La2-xSrxCuO4. In addition, the coexistence of superconducting and antiferromagnetic phases cannot be observed in our samples. The interrelation between the transition temperature and the treatment conditions such as temperature and time is discussed. (c) 2005 Elsevier B.V. All rights reserved.
